Trans 131.01(1)(1) Statutory authority. As authorized by ss. 110.06, 110.20 (9) and 227.11 (2) (a), Stats., the purpose of this chapter is to establish the department’s administrative interpretation of s. 110.20, Stats., relating to a motor vehicle emissions inspection program. Trans 131.01(2)(2) Applicability. This chapter applies to all nonexempt vehicles customarily kept in those counties certified by the department of natural resources under s. 110.20 (5) (a), Stats. It also applies to all nonexempt vehicles customarily kept in any county whose board of supervisors has adopted a resolution under s. 110.20 (5) (b), Stats., requesting the department establish an inspection and maintenance program, and applies to any nonexempt vehicle which a person presents for a voluntary inspection at an inspection station pursuant to s. 110.20 (7), Stats., and s. Trans 131.07. For purposes of determining where a vehicle is customarily kept, the county of domicile as indicated by the vehicle owner and contained in the department’s title data base shall be used. In the absence of an indicated county of domicile, the owner or lessee’s post office address shall be used to determine county of domicile. The department may determine whether the vehicle domicile location is consistent with the owner or lessee’s post office address or with other information that indicates the customary location of the vehicle. The department may change a vehicle domicile location in department title records to make it consistent with the results of its determination, and may require the vehicle to undergo emission inspection as required in this chapter. If the vehicle owner or lessee disputes the department’s determination, the vehicle owner or lessee may present evidence satisfactory to the department of the correct vehicle domicile location. The department decision as to correct vehicle domicile location shall be the final decision of the department.
